Generation of the Camptothecin Scaffold by a Flavin‐Catalyzed Photooxidative Skeletal Reorganization

open access: yesAngewandte Chemie International Edition, EarlyView.
The biosynthetic pathway of the anticancer drug precursor camptothecin involves an enigmatic skeletal reorganization from a 6/5/6 tetrahydro‐β‐carboline to a 6/6/5 pyrroloquinoline ring system. Here, we show that this transformation can be achieved by photooxidation with flavin cofactors, such as flavin mononucleotide (FMN) as catalysts.

Microsomal epoxide hydrolase polymorphisms

open access: yesMolecular Medicine Reports, 2010
Microsomal epoxide hydrolase plays a dual role in the activation and detoxification of carcinogenic compounds. Two polymorphic sites have been described in exons 3 and 4 of the microsomal epoxide hydrolase gene that change tyrosine residue 113 to histidine (Tyr113His) and histidine 139 to arginine (His139Arg), respectively.

Synthetic Strategies for Activity‐Based Probes to Decode Ubiquitin‐Like Modifiers

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT Ubiquitin‐like proteins (Ubls) such as SUMO, NEDD8, ISG15, URM1, UFM1, FAT10, ATG8/ATG12, and FUBI are essential regulators of cellular homeostasis, controlling processes from protein stability and trafficking to immune signaling and autophagy.

Hybrid Macrocyclic Peptides — Synthetic Strategies to Diversify and Cyclize Peptide Libraries in Phage Display Selections

open access: yesChemistry – A European Journal, EarlyView.
Hybrid macrocyclic peptides unite genetically encoded peptide libraries with the structural complexity of synthetic small molecules. This Review critically analyzes phage‐compatible cyclization and diversification chemistries, highlights emerging opportunities beyond traditional cysteine‐based approaches, and outlines how future advances may enable the

Cholesterol epoxide hydrolase and cancer

open access: yesCurrent Opinion in Pharmacology, 2012
Cholesterol epoxide hydrolase (ChEH) catalyzes the hydration of cholesterol-5,6-epoxides (5,6-EC) into cholestane-3β,5α,6β-triol. ChEH is a hetero-oligomeric complex called the anti-estrogen binding site (AEBS) comprising 3β-hydroxysterol-Δ(8)-Δ(7)-isomerase (D8D7I) and 3β-hydroxysterol-Δ(7)-reductase (DHCR7).

The gut microbiome and drug‐resistant epilepsy: Microbiome–antiseizure medication interactions and implications for pharmacoresistance

open access: yesEpilepsia Open, EarlyView.
Abstract Drug‐resistant epilepsy (DRE) affects approximately one‐third of patients with epilepsy and represents a major unmet clinical need. While traditional hypotheses of pharmacoresistance have focused on alterations in drug targets, efflux transporter overexpression, and intrinsic disease severity, the gut microbiome has recently emerged as a ...

Soluble epoxide hydrolase inhibition alleviates chemotherapy induced neuropathic pain

open access: yesFrontiers in Pain Research, 2023
Chemotherapy induced peripheral neuropathy (CIPN) is a particularly pernicious form of neuropathy and the associated pain is the primary dose-limiting factor of life-prolonging chemotherapy treatment.
